Innate immunity, also called natural immunity, is the
first line of defense. This type of defense is in place
define innate immunity before an infection takes place and can function
immediately. It is comprised of physical, chemical,
cellular, and molecular defenses.
The skin's design makes it a strong physical barrier. It
has closely packed cells in multiple layers that are
continuously being shed. Keratin covers the skin,

destroy them.

Macrophages have a long life span, reside in the
